  • Yea of course it is a “software” feature every motor in a ev is controlled by software that switches power electronics. “Dissconnecting” the phases of the motor so it wont recoup while is spins is still neutral. Or is “neutral” only a thing that a automatic transmission can do? If i put my manual out of gear is it then not in neutral? People dont want the manufacturer to install a clutch to physicly dissconnect the motors from the drivetrain but they want to be able to let the car roll without it braking by recharging the battery or dumping the power as heat into the powerstage.

    And by the way yes most evs still habe gears just with a fixed ratio because if the motor was directly connected to your axle full motor rpm would be way faster than your max road speed you can drive.




  • I dont think you understand the difference between a lossless file format/encoding algorithm and “losless” recording/storing of signals. If anyone ever speaks of a lossless encoding algorith theyy mean that avter encoding and decoding the input and output will be the same e.g nithing was lost. Why would the recording have annything to do with the lossyness of the encoding algorithm? If the music was made digitally there would be no loss in any sense since the output of your daw or midi file etc is already digital. Btw in general you just cant record any arbitrary analog signal but you can record a lot of it. You will also never in no media be able to store the exact signal. There is always noise always some variation. Even if you store your signal analog there is only so much variance of the magnetic field in a tape and only so many atoms of height difference in the groove of your vynil. The thought of lossless recording is just dumb if you think about it because you change the signal by measuring it annyway so what even is the “original” signal?



  • Dc transmission lines at 10kv? Dc transmission lines make sense when you need to pass a really long distance or you can only use underground cables because those have a much higher capacitaance, i.e. high reaktive currents.

    If you need to supply your rural area or town you will go from some 20kv lines down to lots of 3kv and then 400v lines with multiple transformers everywhere. Dc transmission doesnt make sense here, but supplying a grid from really far away with a single line? Yea.


  • Yea have fun transmitting a decent amount of power with 240v over a meaningfull distance. Also most generators produce ac anyways so why would you recitify it at the generator instead of your device after a transformer? You still need all kinds of different voltages everywhere in your electronics and this means you still need to regulate it.

    I am not shure how the american wirering worls out but to get from 240 to 120 you still need a transformer… or is it 240v between the different phases and then 120 from phase to neutral?


  • It literally says “32 bit RISC-V homemade CPU out of discrete components”.

    I dont know how you would stretch the definition of cpu in form of discrete components but yea current processors also stray from the definition of a alu and a control unit and registers since people call the different cores cpus. But even a Mikrocontroller has a all that.

    You need a cpu to run linux. If you just want to rin a “program” you can do that with logic gates and no alu or control unit but that would limit the form of your program to exactly that circuit.


  • Yea shure you guys think that nasa was able to land something on the moon with either remote control or fully automated and then after a sucessfull landing of a unmanned craft deploy a mirror angled so you can bounce back laser but you also say that PEOPLE were never up there? What is even needed as proof for you people?


  • Well the “super computer” argument is just not good because this wasnt an all purpose computer. This was specially build for this task. There are tons of special purpose chips today that wont be able to do general purpuse computing but crush a beefy pc in special tasks. Video encoding for example or tons of other tasks.
